ART OF MAKING WIRE RODS.

SPECIFICATION forming part of Letters Patent No. 351,365, dated October26, 1886.

Application tiled July 3, 1886. Serial No. 207,037. (No inodell) To aZZwhom it may concern.-

Be it known that I, FRED I-I. DANIELS, a citizen of the United States,residing at \Vorcester, in the county of Vorcester and State ofMassachusetts, have invented certain new and useful Improvements in theArt of Making Vire Rods, of which the following, together with theaccompanying drawing, is a specification, sufficiently full, clear, andexact to enable persons skilled in the art to which this inventionappertains to make and use the same.

The object of my present invention is to produce wire rods with greaterrapidity and economy than by the present employed processes, and toavoid the large percentage of waste occasioned in the rolling of rods bycontinuous method as ordinarily practiced.

My present invention consists in a method of producing or making wirerods from very large or heavy billets, weighing about five or six times(more or less) as much as the weight of billets such as are ordinarilyused for continuous rolling into wire rods, wherein the billet ispartially reduced and intermediately during the rolling or reducingoperations the partially-reduced rod is divided into parts or sections,and the reduction of such parts separately continued and completed byfurther rolling operation; then the separately finished rods are againout into a number of sections of desired length or weight for handling,and said sections separately reeled into coils, the intermediate cuttingoperations being performed while the rod is in a heated condition,- oras it issues from the reducingrolls.

In carrying out my invention I employ apparatus of suitable size andcapacity for heating and working the larger billets. Theheating-furnaces may be of ordinary or any suit able construction, andfor the primary and secondary reduction of the rods trains of rollsmounted and arranged as in the ordinary continuous rolling-mill may beemployed, the leading rolls being adapted for doing heavier work. Theprimary and two or more secondary trains may be arranged substantiallyas illustrated in my Letters Patent No. 292, 794, or in other suitablemanner, if preferred. Reeling mechanism of any suitable kind may beemployed, preferably two or more reels, to receive and coil alternatesections of the rod, and permit time for discharge without allowing therod to accumulate in advance of the reeling.

In the drawing the figure is a diagram illustrative of the nature of myinvention, and showing the arrangement in a mill-plant of a primaryrolling-train, a cutting-off apparatus, a plurality of secondaryrolling-trains, a secondary cutting off apparatus, and reels for coilingthe finished rod.

The details of mountings, gearing, and means of I driving the rolls isnot shown herein, as any person conversant with rolling-mills willreadily understand the same without illustration.

I do not desire to confine my process of making wire rods to anyparticular detail of mechanical devices, as variously-arranged mechanismmay be used to accomplish the various manipulations without change inthe essential feature of my improved method of treat ment.

Referring to the'drawing, A denotes a primary train of reducing-rolls.

B indicates a shearing mechanism or cutters for severing apartially-reduced rod as it comes from the primary reducing-train.

0 indicates a switch for directing the severed sections of rodalternately to the right and left through guides or conductors D D tothe secondary rolling or finishing trains E E.

F indicates a secondary cutting apparatus or shears for severing thefinished rod into sections; and It, It, and R indicate reels orapparatus for coiling the finished rod.

My improved method of making rods is as follows: I take a billet or barof metal weighing six hundred pounds, (more or less,) which, whenproperly heated, is passed through the primary train of rolls A, wherebyit is reduced to a medium size, and in order to obviate the inconvenientelongation the rod is severed into sections by the shears or cut-oft"mechanism, which sections are alternately directed to the right andleft, to be further rolled in one of the several secondary trains,wherein the reduction of the rod is completed, and after which it isagain severed by the shears or cut-off mechanism. F into convenientlengths to form coils of convenient weight for handling, or intosections of, say, about one hundred pounds weight, (more or less,) whichsections are alternately directed to separate reels, as R and It, andthereby coiled up, the coilsection of rod being discharged from one reelduring the time it is being wound onto another, so thatsaid second reelwill be ready to receive the end of the rod when the following sectionis severed, In some instances it may be desirable to sever the rod morefrequently before the secondary rolling, and to coil the rod withoutsevering it after it comes from the secondary train, as indicated by thereel R at the left of the drawing; but ordinarily I consider itpreferable to run the rod through the secondary trains in as longlengths as practical, and to sever the rod into sections to bealternately coiled on separate reels after the rolling is finished.

The advantages gained by this method of working rods are the avoidanceof waste by reason of imperfect portions of rod which have to be cutoff, and also a material advantage in the running and wear of themachinery, the labor and attendance on the mill, and the speed ofproduction.

In my application for Letters Patent, Serial No. 189,791, I havedescribed a process in which rods are rolled from large billets, severedinto sections, and then reeled, while the present application embraces aprocess of rolling rods from large billets, severing them into rods bycontinuous operation, which consists in rolling downa large or heavybillet'to form an extended rod of a size somewhat larger than thefinished size, severing the partiallyreduced rod after it comes from theprimary rolls into sections, alternately directing said sections toseparate sets of finishing-rolls for completing the reduction thereof,then severing the finished rod into sections of convenient weight forhandling, and separately coiling or reeling said sections, substantiallyas setforth.

Witness my hand this 30th day of June, A. D. 1886.
